01/12/2021, 5:53 PMIt would be nice if gui-vista could take some ideas from https://github.com/kropp/kotlin-native-gtk for DSL builder and events/signals
Marshall
01/12/2021, 5:54 PMI haven't closely compared the two however

01/12/2021, 7:36 PM@Marshall yeah definitely! I tried to compile the examples, but on my Fedora it wasn't compile because I have gtk3 header file in another directory in compare to Debian like distros. This is actually also a good question how to solve this problem. Usually you can run the
pkg-configm

01/13/2021, 5:34 AMBeen looking at event handling done by the kotlin-native-gtk library, and found it falls into a common trap ( https://github.com/kropp/kotlin-native-gtk/blob/master/gtk3/src/linuxX64Main/kotlin/signals.kt#L17 ) that many libraries fall into. Creating a StableRef, and assuming that it doesn't need to be closed/freed (via the dispose function - https://kotlinlang.org/api/latest/jvm/stdlib/kotlinx.cinterop/-stable-ref/dispose.html ). This leads to memory leaks which can cause software to crash (eg segfault). Under Kotlin Native's current memory model it isn't possible for a library to automatically manage StableRef's for event handlers, hence wrapping event handlers doesn't work. Hopefully Kotlin Native's new memory model will fix this problem.

01/13/2021, 5:36 AMWould like to make significant changes (improvements) to event handling with GUI Vista, but Kotlin Native's current memory model prevents changes from being made.

01/13/2021, 5:38 AMKotlin Native has a very limited memory leak checker which can detect some issues like StableRef's that haven't been disposed of.
